It has a pure Ku band payload and was used fill the position at 144°East longitude. It provided television signals and business communications services throughout Japan, southern and eastern Asia, and Hawaii.[2][10] Satellite descriptionThe spacecraft was designed and manufactured by then Hughes (now Boeing) on the HSS-601 satellite bus. It had a launch mass of {{convert|3150|kg|abbr=on}} and a 13-year design life. When stowed for launch, it measured {{convert|4|x|3.8|x|2.4|m|abbr=on}}. It had two wings with four solar panels each, that generated 4.5 kW at the end of its design life. When fully deployed, the solar panels spanned {{convert|26.2|m|abbr=on}}, with its antennas in fully extended configuration it was {{convert|7.5|m|abbr=on}} wide.[10] It had a 29-cell NiH2 battery with a power charge of 200Ah. Its propulsion system was composed of an R-4D-11-300 LAE with a thrust of {{convert|490|N|abbr=on}}. It also used had 12 {{convert|22|N|abbr=on}} bipropellant thrusters for station keeping and attitude control. It included enough propellant for orbit circularization and 13 years of operation. Its payload is composed of two {{convert|85|in|m|abbr=on|order=flip}} dual-gridded reflectors and twenty four Ku band transponders powered by TWTA with and output power of 90 Watts. It can configure two 54 MHz transponders into one 114 MHz with an effective 180 Watts.[10][6] The Ku band footprint covered Japan, southern and eastern Asia, and Hawaii. HistorySpace Communications Corporation (SCC) was founded in 1985, the same year as the original companies that later formed JSAT.[20] SCC switched satellite suppliers and on 1995 ordered a satellite from Boeing, Superbird-C.[10]On July 28, 1997 at 01:15:00 UTC, Superbird-C was orbited by an Atlas IIAS launched from Cape Canaveral LC-36B.[10] Superbird-C It was replaced by Superbird-C2 during 2008, at which point it was decommissioned.[23] References1. ^http://www.jsat.net/common/pdf/en/superbird-3.pdf [3][4][5][6][7][8][9][10]2. ^https://www.satbeams.com/satellites?norad=24880 3. ^1 {{cite web |url=http://www.globalsecurity.org/space/world/japan/superbird.htm |title=Superbird |publisher=Global Security |access-date=2016-08-26}} 4. ^1 2 3 4 5 {{cite web |last1=Krebs |first1=Gunter Dirk |title=Superbird C |url=http://space.skyrocket.de/doc_sdat/superbird-c.htm |website=Gunter's Space Page |date=2016-04-21 |access-date=2016-08-26}} 5. ^1 {{cite web |url=http://www.skyperfectjsat.co.jp/en/about/history.html |title=History |publisher=SKY Perfect JSAT Holdings Inc. |access-date=2016-08-26}} 6. ^1 2 {{cite web |url=http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1997-036A |title=Superbird-C Description |publisher=NASA Space Science Data Coordinated Archive |date=27 April 2016 |access-date=2016-08-26}} 7. ^1 {{cite web |url=http://nssdc.gsfc.nasa.gov/nmc/spacecraftOrbit.do?id=1997-036A |title=Superbird-C Launch Information |publisher=NASA Space Science Data Coordinated Archive |date=27 April 2016 |access-date=2016-08-26}} 8. ^1 {{cite web |url=http://www.n2yo.com/satellite/?s=24880 |title=SUPERBIRD C |publisher=n2yo.com |access-date=2016-08-26}} 9. ^1 2 {{cite web |title=Superbird 3 |url=http://www.satbeams.com/satellites?norad=24880 |publisher=Satbeams |access-date=2016-08-26}} 10. ^1 2 {{cite web |url=http://www.superbird.co.jp/english/superbird/c.html |title=Main specifications of SUPERBIRD-C |publisher=Space Communications Corporation |access-date=2016-08-26 |deadurl=bot: unknown |archiveurl=https://web.archive.org/web/20040604064908/http://www.superbird.co.jp/english/superbird/c.html |archivedate=2004-06-04 |df= }} }}{{Portal|Spaceflight}}{{Superbird}}{{Orbital launches in 1997}} 5 : Communications satellites in geostationary orbit|Satellites using the BSS-601 bus|Spacecraft launched in 1997|Communications satellites of Japan|1997 in Japan |
